2 Claims.

This invention aims to provide a' vseeding mechanism, so constructedthat it may be mounted on the frame bars of .a tractor, provision beingmade whereby the device may be assembled with tractor frames ofdifferent widths.

It is within the province oi' the disclosure to improve generally and toenhance the utility of devices Aof that type to which the presentinvention appertains.

With the above and other objects in view, which will appear ,as thedescription proceeds, the invention resides in the combination andarrangement of parts and inthe details of construction hereinafterdescribed and claimed, it

5 being understood that changes in the precise-embodiment of theinvention herein disclosed, may

bevmade .within the scope of what is claimed, without departing from thespirit of the invention.

In the accomparwing drawings:

Fig. 1 shows in side elevation, a tractor equipped with the deviceforming the subject matter of this application; l

Fig. 2 is a front elevation showing a tractor 25 whereon the seedingmechanism is mounted:

Fig. 3 is .a front elevation of the seed box, wherein parts are brokenaway;

Fig. 4 is a section on an enlarged scale on the line 4-4 of Fig. 3.

30 The invention comprises the combination with a tractor including aframe 3, of a seeder attachment, said .attachment comprising a seed boxl, disposed transversely of the frame, and provided in its upperportion, and intermediate its end da walls, with a downwardly-extendedrecess 2receiving the frame, the recessN being formed bypartiallycutting away the side walls of the box, thereby formingopenings between the uncut portions of the side walls. The seed box l isproso vided, on opposite sides of the recess 2, with top strips d. Lids5 extend between the top strips 4 and the outer end walls of the seedbox, the lids being hingedly mounted. Downwardly extended and inwardlyinclined baffles 6 reach i5 across the seed box I, on opposite sides ofthe recess 2 and in the vicinity of the recess. The baiiles 6 terminateshort of the bottom of the seed box I. The bailles 6 serve to preventthe seed in the box from working inward too rapidly,

toward the central part or the recess 2, and, per'- ha'ps, 'nding anexit through the recess.

Closures 1 are located at the sides of the re- A'cess 2. The closures 'Iextend over the top strips d, to prevent leakage, and they-extend, also,over g5 the side walls of the seed box l. It is derable that theclosures 1 can be moved in and out, in order to adapt the seed box totractors, the beams 3 of which are spaced apartat different distances.With this end in view, the side walls of the closures 1 .are providedwith horizontal slots l, receiving bolts 9. mounted in the walls of theseed box I.-

The closures 1 are held against the outer sides of the frame beams byhookv bolts II, engaged through brackets III, bearing against the outersides of the frame beams 3, the brackets being connected by downwardlyconverging (Fig. 1) and outwardly inclined (Fig. 3) draw bolts Il withanchors I2 mounted on the walls of the seed box I.

Seed distributors or depositors I5 are secured to the bottom of the seedbox I, and in the casings of the seed distributors, a main shaft I6 isjournaled'for rotation. l'he shaft I6 is rotated in -any conventional orappropriate way, for instance by an operative connection I8 between theshaft Il and the rear tractor axle 40.

The'operation of the device will be understood readily from what hasbeen stated hereinbefore, .but by way of recapitulation,'the closures 1can be moved in and out, and be secured in place by the bolts 9, toadapt the seed box I to tractor frames of different widths, the closuresbeing connected to the trame bars l by the hook bolts I I, and the seedbox being held in place, further, by the brackets lo, the draw bolts i4andl the anchors I2.

The seed in the end portions oi the box I moves inwardly, beneath thebailles 5, and passes to the seed distributors or broadcasters I5. 'I'hebroadcasters are operated by the shaft I6. The-shaft I6 derives itsmotion from the rear axle Il ofthe tractor, through The device formingapplication is simple in constructie but it affords means whereby a seedbox transversely oi', and upon, tractor frames of different widths,novel means being supplied for bringing about a distribution andspreading the seed.

VIt will be noted that the shape of the seed box provides increasedcapacity adjacent the recess 2 so that the box will empty uniformlythroughout its entire length, the bales 6 serving to retain sufcientseed to supply that portion of the seed .l box otherwise rendereddeilcient by reason of the recess 2.

Having thus described the invention, what is claimed is:

1. The combination with a tractor including a may be heldv the mechanismindicated at I8. 'Y

the ysubject matter of thisv adjustment, to accommodate tractor framesoi dierent widths, means for securing the box to the tractor frame, aseed depositor carried by the` box, and means for operating thedepositor. l 2. The combination with a tractor including a frame, of aseeder attachment, said attachment comprising a seed box disposedtransversely of the frame and provided in its upper portion, andintermediate its end walls, with a downwardlyextended recess receivingthe trame, the recess being formed by partially cutting away the sidewalls of the box', thereby forming openings between the uncut portionsof the side walls, adjustable closures for the openings, brackets,anchors on the seed box, draw connections assembled with the bracketsand the anchors, connec tors for Joining the brackets with the frame oithe tractor, means for mounting the closures on the box for in and outadjustment, to accommodate tractor frames oi' diii'erent widths, .a seeddepositar carried by the box, and means operating the depositor. y
